Build awesome command-line applications in Ruby 2. Control your computer, simplify your life.

""Some command-line applications save time and are a joy to use. Others just make you want to tear your hair out. David Copeland has written a guide to writing the kind of command-line apps that will make your users want to hug you. From providing a humane command-line interface, to being self-documenting, to integrating seamlessly with the rest of the command-line universe--this book will show you how to take your scripts from adequate to awesome.""--Avdi Grimm, Ruby developer, author, Exceptional Ruby, and blogger, Virtuous Code ""This book proves that text mode is not the just the domain of batch scripts and glue code. Beyond the extensive survey of current Ruby CLI tools, David brings an unmatched focus on user experience and testing. Every full-stack developer should learn how to build the kinds of apps covered in this book.""--Wynn Netherland, CTO, Pure Charity ""I know of no other Ruby book that covers the content in this useful work, especially with its eye toward making Ruby command-line applications better citizens.""--Noel Rappin, Senior engineer at Groupon and author, Rails Test Prescriptions
